Question

$H_1^1$, $H_1^2$, and $H_1^3$ are examples of isobars.

• A. True
• B. False

Answer 1

The correct option is B

False

Isotopes have the same atomic number (same number of protons) and different atomic masses. $H_1^1$, $H_1^2$, $H_1^3$ have 1 proton each, hence they are isotopes, whereas isobars have same atomic masses.
